XRAY just released this new servo mount for their T3. It basically floats the servo off the chassis. Pretty cool!

The new Center Servo Mount is made from high-quality, CNC-machined graphite
and it allows the servo to be mounted to the chassis without touching
it. The servo is mounted using three stands and without any other
modifications. With this new servo mounting method, unwanted chassis
tweak is eliminated while at the same time it provides more overall
traction. The new servo mounting position improves the balance of the car
as the servo is mounted more in the center of the chassis.

• High-quality, CNC-machined graphite
